inv() doesn't generate the correct values

[waynecd]

Hi,

With two charts open, a 3 min "ES #F" with a MACD(12,26,9) study for comparison and a 55T "ES #F" with the following efs running I get very different values for the *.getValue(0) for each chart. I have also used the sym(...) but it gives me the same values as the inv(...), both different from the 3 min chart values. Both charts have the same time interval, I've used 3 day dynamic for both and also tried 3 day 9:30-16:15. The 3 min chart MACD most recent value was 1.79 but the 55T chart values for inv(3) of MACD was -6.40985839...

//this is run on a 55T "ES#F" chart
debugClear();
function preMain() {

    setPriceStudy(false);
    }
function main(){
    SymMACD = macd(12,26,9,inv(3));
    SymMACDSignal = macdSignal(0,0,0,inv(3));
    if(getBarState() == BARSTATE_CURRENTBAR) {
        debugPrintln(SymMACD.getValue(0));
    }
} 

Any help is appreciated.

What MACD study were you using for comparison? The one in Basic Studies?

yes it was.

Did you make sure that in the Basic Studies MACD you were using an exponential average for the Oscillator and Signal lines? From what I am seeing at my end your script is returning the same values when using the exponential average

I answered too fast at first when I said yes. I checked the test page. I used the same test script without the inv() or sym(). So it should have used the default. I will check against the "Basic Studies" version using sma and ema to see if it matters.

Alexis,

I spent 2 hours last night testing it different ways including rebooting eSignal in case I had a bad server.

I just tested it after your reply and MACD for both charts were similar, not exact since there are many 55T bars within a 3 min bar but close.

I'll continue to test it at different hours to see if it is an intermitent issue.

Thanks so much for your follow-up

When you are returning a value then the real time plot on each 55T bar will represent the value of the 3 minute MACD at the time the 55T bar was completed which is not necessarily the same as the current value of the MACD. The value on the current 55T bar however will match that of the 3 minute MACD.
